If you're not already aware of this you can earn donator points by getting people to sign up for Hogwarts Live via your referral link. I've recently changed everyone's referral links to make them easier to remember. While the old referral links still work, it'd be nice if you could start giving out the new easy-to-remember referral links, which look like this:

http://hogwartslive.com/r/Username

Please note Username should be replaced with the name you use to login (i.e. the name that comes after Firstyeargirl or whatever your title happens to be); for example my referral link would be: http://hogwartslive.com/r/Danilo

By giving your friends this link you will automagically receive 50 points every time one of them reaches level 10.

There's more about this on the Referrals page in the Prefect's Lounge.
